The Ford Mustangs starts at $19,995. That is the base price. The Mustang Shelby GT 500 starts at $46,500.
they start around 20 grand and can go up to 50 it really depends on what you are looking for in the trim or if you want all the little bells and whistles lol or it the price could depend alot on the condition of the car or the milage
If you shop around there are good deals out there. I bought mine brand new for $19K. List price was $22,650 for the Pony Package, but I had a lot of discounts. There are some used GT's that have about 27K miles on it for about the same price.
base v6 is $7,675-$12,425
